Using Rsync to Transfer Files to a Cloudvue Gateway

Description 

At times it may be necessary to move files to a Cloudvue Gateway and while other tools such as SCP or MobaXterm can usually manage the job, rsync can track progress and resume after an interruption which can be particularly useful when transferring large files like the latest Cloudvue software or on slow or unstable connections.

Product

  • Cloudvue Gateway

Solution

The command structure is:

rsync -p -e ‘ssh -p [PORT]’ [PATH/FILENAME] smartvue@[IPADDRESS]:/home/smartvue
  • -P  option will force rsync to show a progress bar and keep partially transferred files. 
  • -e  option allows you to specify a different listening port on the remote host
  • ‘ssh – p [PORT]’  Specifies that ssh be used through a specific port number, use 7627 if local or whatever port was assigned in Cloudvue Manager when setting up the tunnel
  • [PATH/FILENAME]  The local path and  file name to be transferred
  • [IPADDRESS]  The IP address of the Cloudvue Gateway, the LAN IP if local or localhost when tunneling
  • :/home/smartvue  The smartvue home folder on Cloudvue Gateways

Note: When tunneling you must first establish the tunnel. You will then need to open a 2nd instance of WSL or terminal to run the rsync commands.

Examples

In the following examples a file named “22.9.2-smartvue-x64-production.tar.bz2” located in “/home/joakest/tunneling/” is transferred to the gateways smartvue users home folder.

Local Connection 

$ rsync -P -e 'ssh -p 7627' /home/joakest/tunneling/22.9.2-smartvue-x64-production.tar.bz2 smartvue@192.168.1.180:/home/smartvue
smartvue@localhost's password:
22.9.2-smartvue-x64-production.tar.bz2
     200,493,957 100%  390.99MB/s    0:00:00 (xfr#1, to-chk=0/1)
  • When prompted enter the SSH password found in Cloudvue Manager.
  • The progress of the file transfer will display, and the prompt will return when completed.

Tunnel Connection 

$ rsync -P -e 'ssh -p 8346' 22.9.2-smartvue-x64-production.tar.bz2 smartvue@localhost:/home/smartvue
The authenticity of host '[localhost]:8346 ([127.0.0.1]:8346)' can't be established.
ED25519 key fingerprint is SHA256:nw6P03KIwsjiKfy2fkJJjRUSi4dJA6gwLyd7/+0Fz0Y.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

Warning: Permanently added '[localhost]:8346' (ED25519) to the list of known hosts.

smartvue@localhost's password:
22.9.2-smartvue-x64-production.tar.bz2
    200,493,957 100%  249.79kB/s    0:13:03 (xfr#1, to-chk=0/1)
  • Since this is the first time a ssh connection has been established to this NVR from the local machine the authenticity warning will appear.
  • Continue by typing in “yes” and pressing enter.

Adding an Authorized Public SSH Key to a C2C

Description 

SSH access to Cloudvue C2C devices  depends  on  RSA public/private key pairs.  Public keys for L3 Cloudvue support were added into the Cloudvue production software with the release of 22.9.0 in January of 2023.   The following instructions can be used to temporarily add a public ssh key to a C2C device.  SSH public keys added in this fashion will not survive a normal Cloudvue software update.

Product 

  • Cloudvue C2C

Solution

Prerequisites

  • If one does not already exist you will need to generate an ssh key pair, see Knowledge Base Article #13051 “Cloudvue SSH Tunneling” for details
  • A copy of your public key, the contents of (~/.ssh/id_rsa.pub)

Find a Buddy

You will need to get the assistance of someone who already has ssh access to the camera to SSH into the camera and make the necessary changes

Extract Cloudvue Software

Run the following command on the C2C to extract the contents of the Cloudvue software tarball into a temporary folder for editing:

mkdir -p /tmp/tBall && tar -xf smartvue.tar.gz -C /tmp/tBall

Add Public Key

Edit the authorized_keys file and add the new public key using vi

NOTE: vi is the only text editor available

vi /tmp/tBall/home/smartvue/.ssh/authorized_keys
  • Each authorized users will be listed along with their public ssh-rsa key (see example)
  • Insert your information at the bottom of this file beginning with a comment “#” and your name then followed by a line with your public key
  • How you paste will depend  on the program you are using to SSH. In PuTTY it’s just right clicking on the window, in other terminals you may need to right-click and then choose paste in the menu that pops up.
  • vi commands
    • G – Uppercase letter “G” goes to the bottom of the file
    • o – lowercase letter “o” inserts a line below the current line and goes into editing mode
    • ⏎ – Enter key creates a new line below the current one (just putting this here to be thorough)
    • ␛ – Escape key exits “insert mode” in vi
    • :wq⏎ – colon opens up a prompt to type a command, the w  stands for “write” and will save the changes, the q stands for “quit” and will exit vi, Enter key runs the command
    • q!⏎ – If you ever need to quit without saving, leave out the w and add an ! after the q (that tells it to force quit ignoring any changes), Enter key runs the command

Recreate Tarball

Use the following command to recreate the cloudvue software tarball and cleanup temporary files

cd /tmp/tBall && tar -czf ~/smartvue.tar.gz * && cd ~ && rm -rf /tmp/tBall

Install the Cloudvue Software

This will apply the new changes.  A reboot is not necessary since we aren’t modifying any running services

tar -xf ~/smartvue.tar.gz -C /

Manually Calculating the SSH Password for a Cloudvue Device

*** INTERNAL USE ***

Description 

The following instructions can be used to manually calculate the ssh password for a Cloudvue video device.

Product 

  • Cloudvue Gateway
  • C2C

Solution

Cloudvue Gateway

The ssh password is the first 32 characters of the MD5 Hash returned when using the following combination

MAC + Version + 3cadcddd84a94e1014f6a9bfeeecfd6

Where MAC is the MAC address of the device in all CAPS and Version is the version of Cloudvue Software the gateway is running

Linux

$ echo -n AC1F6BB04DDC22.9.0a3cadcddd84a94e1014f6a9bfeeecfd6 | md5sum | cut -c 1-32 8d30ee28cc2e0a736e4da9568a3a2367
$ 8d30ee28cc2e0a736e4da9568a3a2367

C2C

The ssh password, while similar to the Cloudvue Gateway, uses only the first 16 characters of the MD5 Hash returned when using the following combination

MAC + Version + 3cadcddd84a94e1014f6a9bfeeecfd6

Where MAC is the MAC address of the device in all CAPS and Version is the version of Cloudvue Software the C2C device is running

Linux 

$ echo -n 0050F96C05B122.9.0a3cadcddd84a94e1014f6a9bfeeecfd6 | md5sum | cut -c 1-16
